I have homework and i dont know how to find it so please

Add all the numbers together to get the sum.

Divide the sum by the number of numbers to get the mean.

so you have

1,2,3,4, that is 10. divide ten by four. because there are 4 numbers.

you get 2.5. Take each number and subtract 2.5. Discard all the negatives from the pile. So in essence you are taking the above example and subtracting 2.5 from 3 and 4 because the other two are going to be negative. so the answer is 3 - 2.5 and 4 - 2.5 which is 2. then take that 2 and divide by the number of items that you subtracted from which is 2. 2/2 is 1. one is the mean standard deviation.

Mean absolute deviation.

Let's break it down into its components.

Mean - Average

Absolute - absolute value - sign doesn't matter - if negative, make positive

Deviation - difference from the mean

Let's do an example. Population 3 7 4 2. Total 16. Mean (Average) 16/4 = 4.

Deviations

3 - 4 = -1 absolute value 1

7 - 4 = 3

4 - 4 = 0

2 - 4 = -2 absolute value 2

Sum of these deviations 1 + 3 + 0 + 2 = 6

Mean (average) of these deviations is 6 / 4 = 1.5.

Good luck,

Paul

The mean is the arithmetic average, so add up all the numbers and divide by the number of numbers.

The standard deviation is a little more involved. The formula and example are explained here:

Good luck.

About 5.23. If this is homework, be sure to show your work.

It is a value of deviation regardless of sign. That is, negative deviations are considered along with positive deviations.

The classic definition of a deviation is the difference of a value from the standard, average or norm.

As the name says, it's the mean of the absolute deviations. See http://en.wikipedia.org/wiki/Absolute_deviation

Hello Dear

Mean deviation is calculated by the following steps:

1. Add all the numbers and then divide by total number of values. That is take a mean.

2. Then subtract the mean from each values and ADD them all

3. then the added answer must be divided by the total number of values. and you get the Mean devaition.

I solved your problem here in steps:

**Step 1:**

(121+122+123+124+125+126) / 6 Equals to 102.6

**Step 2:**

(121-102.6) + (122-102.6) ...... +(126-102.6)

=125.4

**Step 3:**

125.4/6 = 20.9 is the MEAN DEVIATION

Hope so this will help you.
